“…For steel-on-steel sliding contacts, especially under dry sliding conditions, the deformation and microstructure evolution are of great significance to the tribological behavior of a tribosystem. Those evolutions of subsurface microstructure are crucial in determining the material removal processes [ 4 , 5 , 6 ]. Additionally, the microhardness and microstructure of sliding pairs seriously affect the tribology behavior [ 7 , 8 , 9 ].…”

In this paper, the tribological behavior of 316L stainless steel with heterogeneous lamella structure (HLS), prepared through 85% cold rolling technology and subsequent annealing treatment (750 °C, 10 min), were conducted on a ball-on-disc tribometer under different normal loads in dry ambient air conditions. The morphologies, structures, and compositions of the raw and worn surfaces were analyzed by 3D surface profilometer, XRD, SEM, EDS and TEM. Based on this, the results showed that the HLS 316L stainless steel samples exhibited lower and more steady friction coefficients than coarse-grained samples, especially under higher loads, which can be attributed to the existence of numerous oxidative particles across sliding interfaces. However, the wear resistance of HLS 316L stainless steel sample was a little weakened compared to that of the coarse-grained sample under a normal load of 5 N. When the load increases up to 15 N, an obviously decreased wear resistance was found for the HLS of the 316L stainless steel sample, which was 50% lower than that of coarse-grained sample. This can be ascribed to the more severe oxidative and abrasive wear performance of HLS 316L stainless steel sample under dry sliding conditions.

“…However, in Figure 19c, the worn surface is debris-free due to the lubricative role of h-BN as well as load distribution of TiB 2 to lower the material removal. In the other words, by acting as a solid lubricant, h-BN forms a tribo-film on the worn surface and creates a smoother surface [157]. Hence, it is expected that the presence of wear debris shown in Figure 19b is due to the absence of h-BN.…”

“…The result of a ball-on-disk wear testing revealed a good wear resistance of Ni3Al/h-BN with a COF of 0.22-0.26 while pure Ni3Al showed the range of 0.29-0.33. The ultimate anti-friction and high wear resistivity of the composites was shown to be high, attributing to the higher density of dislocation, mainly Orowan's mechanism [157] in which BNNPs are pulled out and bridged [12] (Figure 19e). As a result, lower shear stress associated with the addition of BNNPs and their self-lubrication characteristic enhanced the weight loss resistance.…”

Recent Progress in the Study of Thermal Properties and Tribological Behaviors of Hexagonal Boron Nitride-Reinforced Composites

Ever-increasing significance of composite materials with high thermal conductivity, low thermal expansion coefficient and high optical bandgap over the last decade, have proved their indispensable roles in a wide range of applications. Hexagonal boron nitride (h-BN), a layered material having a high thermal conductivity along the planes and the band gap of 5.9 eV, has always been a promising candidate to provide superior heat transfer with minimal phonon scattering through the system. Hence, extensive researches have been devoted to improving the thermal conductivity of different matrices by using h-BN fillers. Apart from that, lubrication property of h-BN has also been extensively researched, demonstrating the effectivity of this layered structure in reduction of friction coefficient, increasing wear resistance and cost-effectivity of the process. Herein, an in-depth discussion of thermal and tribological properties of the reinforced composite by h-BN will be provided, focusing on the recent progress and future trends.

“…An addition of hBN particle helps easy shearing over the sliding surface, thereby reducing friction through the formation of a tribolayer. 18,19 On the other hand, the hBN addition reduces the mechanical properties of the composite. During the development of tribocomposite material, all these factors are taken into consideration for a selection of reinforcement level.…”

This paper reports on the effect of ZrB2 and hBN solid lubricant particles on the dry sliding wear behaviour of the AA7075 composite, fabricated by stir-squeeze cast technique. ZrB2 and hBN at levels of 5 wt% were chosen as reinforcements for the study. The optical microscope images revealed uniform distribution of particles and a low order of porosity in microstructure, possibly due to the squeeze pressure. The ZrB2 particles reinforced composite (AZ) showed an improvement in hardness compared to as-cast (A0) and hBN containing composite (AH). A minor reduction in the hardness of ZrB2–hBN hybrid composite (AZH) was observed. This is attributed to changes in the hardness induced by the individual ZrB2 and hBN particles. The hybrid composite (AZH) exhibits a superior wear resistance, possibly due to the formation of good quality B2O3 and H3BO3 self-lubricating film.
